The liberal activist group MoveOn.org is targeting three Democratic Finance Committee Senators over their opposition to the public insurance option, with radio ads set to air in the Members’ home states beginning on Thursday.MoveOn.org is going after Finance Chairman Max Baucus (Mont.), Budget Chairman Kent Conrad (N.D.) and Agriculture, Nutrition and Forestry Chairman Blanche Lincoln (Ark.). All three Democrats voted against two separate public insurance option amendments during Tuesday’s session of the Finance health care markup. The proposals were offered by Democratic Sens. Jay Rockefeller (W.Va.) and Charles Schumer (N.Y.).“The vast majority of Americans want the choice of a public option — the best way to lower costs and expand quality health care to more Americans. Sens. Conrad, Lincoln and Baucus are out of step with the country and their political party and need to be held accountable,— Justin Ruben, executive director of MoveOn.org, said in a statement. “MoveOn’s five million members expect the Democrats in Congress to deliver on the promise of change that got them elected.—The Finance markup of Baucus’ $900 billion health care package continued on Wednesday. The panel planned to recess at 4:45 p.m. for floor votes and a dinner break, and reconvene at 6:30 p.m. Another late night is expected, and Members look to try to wrap up work on the measure by the end of the week.
